DISK-HARRCW MECHANISM.

Application filed July 7, 1919. Serial No. 309,009,

This invention relates to improvements in dish harrows, particularly those which have long with numerous disks which engage powerfully with the earth; and resist movements from one angle to another; and especialiy in dish harrow mechanisms of the tandem class each having two or more pairs or such gangs, each pair mounted in a :trame7 and the two frames connected and drawn to- 10 gether.

'.ihe gangs of these harrovs require trequent adjustment from one angle to another relativeliY to each other and to the line of draft and when long. as they are, in the engine drawn tandem. har-rows, demand oonsiderable power for the adjustment.

@ne of the obj of the present invention to provide tor varying' or adjustiinb)` the angles or the dissi gangs by means ol" power derivee from the draft devices and have it acconrplirhed in such way that where there but one operator for an apparatus the changing' ot the angle et' the lgangs will not divert his attention from controlling the entire apparatus.

yihe two Jrront disk gangs are attached to this frame. Each gang comprises a square shaft 6 carrying` disks 7 spaced along the shaft by the usual spreaders S. The numeral 9 indicates a buli'er plate or boss engaging with the shatt 6 at its inner end. (See Fig. 4l.) At its outer end shaft 6 is threaded to engage with nut l0 by which the disks7 spools and shaft are all tightly fastened together.

Each gang has an outer bearing ll, an inner bearing l2 and an intern'iediate bearing 123. Each side bar 3 of the i'rame is, at its rear end, turned backward, and is connected to one of the intermediate gang hearings 13. The latter has lips l-lw and each lip has a slot lo. The end of the bar 8 lits between the lips and has a coupling pivot pin or bolt l5 which passes through the slots. rlhese connecting` devices permit the gangs, as entireties, to more endwise, inward or outward, in correspondence with the angling,` adjustments of the and the huli'er plates or bosses 9 are permitted to he in Contact and bear against each other, one zang thus resisting the inward thrust ol the other.

The benirimg` boxes of each gang also support the scrupers (32 and their carrying` bar 2J. lllach bearinu` has a s'alulard or upright 28, secured thereto7 bent backward at its upper end. The rufraper bar 29 rests upon the u end parts oi1 the standards and is sered to eael. et alieni by a clamping U- bolt 2f The scrapers do not roel; but are lixed in position. Each blade ($2 is wide and its edge covers enough ot the radius of a disk to insure proper cleaning. It is formed olsheet metal and lower end edge is cut on an inclined line. From the line et Contact with the disk face it extends outward (from the roncave face et the disk) and upward to provide clearance between it and the disk and to prevent a clogging with trash. At the upper end oi the inelined part the shank part is bent to extend almost directly upward as shown in Fin". 5. The edges of this appro-Ximately vertical part are folded or bent sharply around lines longitudinal of the shank, as indicated at 62, to provide stiiiness.

The numeral 41 indicates the usual wood bushing mounted within the bearing 12. 1t surrounds and engages with the rotating sleeve part of the spreader. The numeral 44 indicates a grease cup and is connected by a tube with the bearing 12, and furnishes lubricant therefor. Similar grease cups are provided for all of the harrow bearings.

The rack bar is curved horizontally on lines approximately concentric with the gang pivot at 15.

lt is lowered and raised as follows: rlhe gang bearing l2 has an upwardly extending bracket 27. The numeral 33 indicates a lever pivoted at 34 to a bracket 30 secured to the bracket 27. The numeral 36 indicates a bifurcated clip pivotally connected at 35 to the lever This slip fits loosely see Fig. 4) around the side edges ot the top lange of the rack bar 23, the rack sliding freely through the clip, but being` supported vertically thereby. A spring 37 having one end fixed toI the bracket 27 and the other end attached to the lever 33 acts to normally throw the upper end ot the lever backward and to draw upward on the clip 36. The lever 33 can, at opt-ion, be moved in the opposite direction by a cord 38 extending to the engine platform. W'hen the operator desires to lower the rack to the position of engagement with the gear 22 he exerts a pull on the cord 33 and the upper end ot the lever 33 is drawn forward against the tension of spring 37. Vvlhen he desires to stop the action of the gear in the rack he merely releases the cord 38, whereupon the spring 37 disengages the teeth et the rar.: from the gear. lVhen the rack in its uppermost position the springs 19 are prevented Jfrom drawing the link bar 17 and thel inner ends of the gangs forward, for the rack 23 is 'provided with a series of stops 32 respectively adapted to engage with a lixed step 3l, on the gang, here shownas attached to the bracket 27 on the bearing box 12.

After the operator releases the cord 33 and the spring 37 pulls the rack up from the gear 22 to its uppermost position one of the teeth 32 instantly engages with and bears against the stop 31 and thus locks together the rack, the bearii'ig 1 2 and the gang, and so long as the rack abutsragainst the main frame the bearing 12 and its are prevented from moving `torward under the tension of spring 19. The stops 32, in number and position, correspond 1o the several positions of angling adjustnient ier the gangs.

rlhere is a neutral position for the rack between its uppermost position where its teeth 32 engage with the stop 31 and its lowermost position where its teeth 25 engage with the teeth 26 of the gear, and when the operator desires that the two of the pair should be again brought to transverse alignment he brings the rack to this neutral position. To do this he pulls slightly on the card 33 and draws the lever 33 only a short distance forward, merely far enough, to lower the rack to the line where is inactive. TWhile it is being held at that line the stop 31, the box 12, (which carries the stop) and the inner end ot the gang, are free to move forward, and they commence immediately to so move under the action ot the springs 19, the movement continuino' until the stop 21 contacts with the frameoar 1, which occurs when the two are in tranverse alignn'ient.

The rear element of the apparatus has a frame comprising an arched bar 46 at the front end which is in the central vertical longitudinal planes of the machine, its upper part being above the disks and frames of the 'front element and its downward extending part 46o being pivoted at 47 to the front frame, The numerals 46, 46 indicate downward and backward inclined side bars of the rear frame, having their front ends rigidly secured to the central bar element 46a and their rear ends carried down te the horizontal planes of the rear gang axles. rfhe numerals 50, 5G indicate frame bars rigidly secured to the bars 46 and Yform part et the central bar 46a, and at their rear ends they are rigidly secured to the forward ends of the bars 49.

Each rear gang comprises parts quite similar to those constituting a front gang including` boxes at the outer ends, boxes at the inner ends and intermediate bearing boxes 48. Each box 48 is secured by a pivot to the outer parts of the rear frame. To each inner box 55 there pivoted a dragbar or linkI These in turn are pivoted to swinging links or arms 51 and the latter are connected by a crossbar 52 to which is secured a spring 53, adjustably 'fastened to the upper and central part 46:L ot the rear traine. @ne oi' the arms 51 has an. extension 51L shaped and positioned to Contact with the brace 50 and stop the forward movement ot the dragbars 54 and the inner ends of the rear gangs.

The links 54 and the inner ends ot the rear axles being all connected together, both of the gangs will be moved simultaneously and .in the same direction when either of the dragbars is moved.

At 56 there is a rack pivoted to the trame and having its rear end part extended back over the inner end of one of the gang axles. Immediately below it there is a gear on the axle. The numeral 57 indicates a cord extending to the engine platform and this is adapted to raise and lower the rack 5G in the way above described.

It is not necessary to describe all of the parts in detail which constitute this set ot devices, they being substantially similar to Fill' the rook, 5l, the geur 22 end the edjaieeiit adjuerts fomllined with the relies ol the front element. led the deteils will lbe readily iur derstood.` le this cese, however, the rech her is ourved reversely iii comparison with the trent rook, the Crirve heini;` ori lines approxiu'iotely eo'heentrie with the pivot whieh eorineots the gang axle to the reu'ie.
